PRESERVED-FOOD TIN.

Specification of Letters Patent. I

T0 at 'LU/ 1107Tb'it may concern:

Be .it known that I, Josnr AMTMANN, a sub- 1 useful Improvements in Preserved-Food Tins, of which the following is a specification.

My invention relates to the usual cylindric or square tins wherein preserved food is shipped; and it has for its purpose better to adapt the said tins for having their contents heated. The usual methods of heating such tins consist in either immersing the tin in hot water or insubjecting it to the direct action of a flame. In each case a comparatively long time is required to heat the contents of the direct action of a flame there is the liability of burning the portions of food adjacent to the bottom or sides of the tins.

My invention has for its object to overcome this dil'liculty.

To this end the bottom of the tin is provided with a central conical recess protrud ing to a'small extent through the top of the tin,-which recess is provided with double sides forming a water-chamber. The 1notruding upper end of the water-chamber is closed, but must be perforated or cut away before the can is subjected to heat in order to allow water and steam to escape. For heating the tin it is placed upon a support which allows a free space for the heating-flame In some cases the tin is provided with legs or arms of pliable wire to form a stand or support. A spirit-lamp for heating may advantageously be carried in the recess in the tin.

In the annexed sheet of drawings, Figure l is a sectional elevation of a tin the bottom of which is provided with a double-sided conical recess containing a receptacle for solidified spirit. Fig. 2 is an under side view of the tin, and Fig. 3 is a sectional elevation of the tin supported, by means of its soldered wire legs,

upon the edge of a soldiers mess-tin and having the spirit-lamp burning under it.

It will be seen from Figs. 1 and 2 that the bottom a, of the preserved-food tin is provided with a central circular perforation which is closed by a sheet-metal cone 0, protruding to a small extent through the top or cover I) of the tin. At a small distance from the bottom proper, a, of the tin a second bottom f is arranged, likewise having a central circular berforation and an upwardly-extending s set-metal cone (1, closing the said perforation. The two bottoms a and f and the two sheet-metal cones c and d encompass a chamber g, which is filled with water, to which substances may be added for preventing it from putrefying and freezing. In Figs. 1 and 2 of the drawings a receptacle 72, for solidified spirit is shown inserted into the hollow space of the inner cone d and kept in place therein by a soldered sheet-iron strip The V-shaped wires 1', soldered'to the tin, are intended to be bent sideward in order to form legs or carriers by means of which the tin can be placed upon suitable supports,

l such as stones or the sides of a mess-tin 7c, in the tins to the center, and when sub ected to such a manner that the necessary space for the spirit-receptacle 7b is kept free below the tin. Before kindling the spirit the point of the sheet-metal cone 0 is cut away or pierced in order to allow the water expanded by the heat and afterward the steam to escape.

It is obvious that the conical sheetmetal sides may be replaced by sides of different sh apei"or instance, cylindrical or spheroidal onesobtained from sheet metal by the drawi'ng process, in which case a thin tube must extend from the top of the upper side of the water-chamber through the top of the tin and have its end sealed by solder.

m is a sheet-metal flap destined to be seized by the key for opening the tin.

lVhat I claim, and desire to secure by Let ters Patent of the United States, is

1. In a preserved-food tin, the combination with lateral sides and a top having the usual form, of a double-sided bottom having 'a central recess, a sealed extensionof the upper side of the recess protruding through the top of the tin, and a water filling in the hollow space between the do uble sides, substantially as and for the purpose described.

2. In a preserved-food tin, the combination with lateral sides and a top having the usual form, of a double-sided hottom having a central recess, a sealed extension of the upper side of the recess protruding through the top of the tin, a water filling in the hollow space between the double sides, and a fuelreceptacle inserted into the recess, substantially as and for the purpose set forth.

3. In a preserved-food tin, the combination with lateral sides and a top having the usual form, of a double-sided bottom having In witness whereof I have signed this specia centfal recess, a sealed GXtGllSlOl of the upfioation in presence of two Witnesses.
